Descrição

Aplicação

• A novel premixing strategy for highly sensitive detection of nitrite on paper-based analytical devices.: This study introduces a new premixing method to enhance the sensitivity of nitrite detection using N-(1-naphthyl) ethylenediamine dihydrochloride. The method significantly improves the detection limits and accuracy, making it a valuable tool for various analytical applications (Xu et al., 2024).



• Electrochemical Self-Assembled Gold Nanoparticle SERS Substrate Coupled with Diazotization for Sensitive Detection of Nitrite.: The study demonstrates the use of N-(1-naphthyl) ethylenediamine dihydrochloride to generate azo compounds, that assemble on the surface of AuNP/ITO an electrochemically self-assembled gold nanoparticle substrate for surface-enhanced Raman spectroscopy (SERS), coupled with diazotization, to detect nitrite with high sensitivity (Han et al., 2022).
